New Delhi: The national capital and its adjoining regions have plunged into a “severe” pollution emergency today, January 19, 2026, with the Air Quality Index (AQI) breaching hazardous levels. A toxic combination of dense fog and stagnant wind speeds has turned Delhi-NCR into a virtual gas chamber, forcing authorities to reimpose strict Stage IV GRAP (Graded Response Action Plan) measures.
While the overall AQI for Delhi plummeted to 418 (Severe), specific pockets reported alarmingly higher numbers. Noida has emerged as the most polluted city in the NCR with an AQI of 622, while the Anand Vihar locality in Delhi recorded a shocking 661 (PM2.5-based AQI), significantly above the standard 500 cap.
The Numbers: Where is it Worst?
According to the Central Pollution Control Board (CPCB), over 30 areas in the capital are currently in the “Red Zone” (Severe Category).
Top 5 Most Polluted Hotspots (Jan 19, 7:00 AM):
- Anand Vihar: 661 (Hazardous)
- Noida: 622
- Ghaziabad: 516

Impact on Travel (Important for J&K Flyers): The thick smog layer has significantly reduced visibility to near-zero in many areas.

With the AQI forecast to stay above the 450 threshold for the next 24 hours, the Commission for Air Quality Management (CAQM) has invoked Stage IV restrictions.
- Ban on Construction: Strict ban on construction and demolition activities.
- Vehicle Restrictions: Entry of truck traffic into Delhi (except essential commodities) is restricted. BS-III petrol and BS-IV diesel vehicles are banned.
